Choi Kanghee on MBC "Section TV Entertainment News" that was aired on Friday, said that she was impressed by Hwang Chansung when she was acting with him on "7th Grade Civil," because he wouldn't get easily discouraged on the set. 

She continued on saying "It is okay to be discouraged and shy. However, when I ask if he is alright after the NG due to the pronunciation and all, he would do that." Choi Kang Hee pointed at Hwang Chansung, and he showed a funny pose saying "Overcome!" 

Joo Won then created a laughter by saying "he is one of a kind."
